APPLICATION INFORMATION

Stir 2018 Clear Sealer before application. 2018 Clear Sealer may
be applied by brush, conventional or airless spray. Thinning is not
normally required although on very warm days use Pettit 120
Brushing Thinner at 5-10% by volume to ease brushing and
maintain good flow. When spraying, use Pettit 121 Spraying
Thinner up to 20% by volume. Spray an even, wet coat to
minimize orange peel. Do not apply 2018 Clear Sealer on extremely
humid days or when rain is threatening. Do not apply in
the late afternoon when working outdoors as the wet film may be
adversely affected by dew. On fir or any wood that has a large
hard grain pattern wipe with dry rags while the sealer is wet to
remove the excess from the hard grain areas. 2018 Clear Sealer
is not completely absorbed into the hard grain.

SURFACE PREPARATION

Wood must be clean, dry and properly prepared prior to varnishing
or painting. When sanding wood, always sand with the grain. Use
a vacuum, air hose, or tack rag to remove all traces of sanding
residue. Follow all surface preparation steps carefully, avoiding
shortcuts. Inadequate surface preparation will virtually assure
inadequate performance.

Pettit Old Salem 2018 Sealer for Varnish

5

This sealer was specifically recommended as an undercoat sealer for Epifanes varnish or Gloss Wood Clear products and seems to work very well allowing good varnish build without excess wood absorption or dry spots.
